RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version: kernel-2.6.32-153.el6
Doc Type: Bug Fix
Doc Text:
A kernel panic in the mpt2sas driver could occur on an IBM system using a drive with SMART (Self-Monitoring, Analysis and Reporting Technology) issues. This was because the driver was sending an SEP request while the kernel was in the interrupt context, causing the driver to enter the sleep state. With this update, a fake event is not executed from the interrupt context, assuring the SEP request is properly issued.

Description kashyap 2011-05-04 12:03:28 UTC 
Description of problem:


Version-Release number of selected component (if applicable):


How reproducible:
Possible to reproduce with specific system/hw


Steps to Reproduce:

1. Requires IBM system and drive having SMART issues.
2. Boot using above system and after sometime you can observe kernel crash
in mpt2sas driver

  
Actual results:
There is kernel crash in mpt2sas driver.

Comment 12 Gris Ge 2011-06-14 13:49:56 UTC 
It's hard for us to find a disk with SMART error in Red Hat.
I will try to shake a disk with power on it. Hope it got "Current_Pending_Sector" SMART error.

Can reporter or any partner willing to help us to testing once rpm build ready?

Gris,
Original fix was tested by IBM. We don't have required h/w to test the fix.
Best I can do is verification of patch part of RL6.1
